how do I enable mbed for a nrf51822 breakout board ?
hi guys, I'm working on a nrf51822 breakout board sourced from alibaba.com . I want to enable this breakout board to be programmed through mbed. Ordinarily, the way to program and debug this is through a JLink+Keil platform (that comes packaged with the kit) or to use an mbed enabled mkit (https://mbed.org/forum/platform-39-Nordic-nRF51822-community/topic/4849/?page=1#comment-25003)
Some people have used the Arch-ble (https://mbed.org/users/yihui/notebook/nrf51822-with-pyocd-and-arch/) to do it. Some people have used the STLink/STM32F103 (https://github.com/RIOT-OS/RIOT/wiki/Board:-yunjia-nrf51822) through OpenOCD. A few others look like they have used the LPCXpresso (http://bril-tech.blogspot.co.uk/2014/06/bluetoothsmartmbed-3.html), but I cant be sure since I cant read/translate chinese that well.
Can I use the stlink as an mbed interface to program the nrf51822 ? If someone has done something similar, it would be really helpful to understand the wiring as well as the build. Currently, I'm using https://github.com/sandys/mbed-nrf51-gcc-test/ to use cmake to build the app.
thanks!

You can always export from mbed to an offline toolchain and use that toolchain to do whatever you want. The default settings for an offline project are CMSIS-DAP, so you'll need to change that to Jlink, or Ulink or whatever you're using. This is one option. Also keep in mind that if you're using a tweaked version of the chip you'll need to make the appropriate tweaks in the project settings, (flash space, stack pointer...etc)
Good luck!
Hi Sandeep ss,
I am looking for a nRF51822 breakout board. Couldn't find any in alibaba or aliexpress. Could you provide any link/reference to the one you are referring to?
Thanks!
